The following data shows the weight, in pounds, of 6 bags:

6, 4, 8, 7, 8, 9

What is the value of the mean absolute deviation of the weight of the bags, and what does it represent about the weight of a bag?

1.8 pounds; on average, weight of a bag varies 1.8 pounds from the mean of 7 pounds
1.3 pounds; on average, weight of a bag varies 1.3 pounds from the mean of 7 pounds
1.3 pounds; the weight of 50% of the bags is greater than 1.3 pounds
1.8 pounds; the weight of 50% of the bags is greater than 1.8 pounds

the mean is 8

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
